Abstract
A metallic strap includes two feet soldered to a conductive coating forming part of a heating grid on a glass substrate and, joining those feet, a bridge portion integral with the feet to which a conductor may be affixed for supply of current to the grid. The bridge portion is notched, slotted or perforated to reduce the stresses which differences in thermally induced expansion or contraction between the strap and substrate can impose on the attachment of the strap to the coating.
Claims3
A terminal of a heater grid including conductive strips and bus bands made of a mixture of metallic powder and a frit baked to a rigid insulating support, said terminal comprising two coplanar feet soldered to one of said bus bands, and a strip-shaped bridge portion joined with the feet by shoulder portions and displaced from the plane of said feet, a tab extending laterally from said bridge portion between said shoulder portions with the initial portion of the tab coplanar with the bridge portion, the bridge portion directly between said shoulder portions and in direct lateral alignment with said initial portion of the tab having an opening passing completely therethrough to produce in said bridge portion a region of smaller lateral cross section than other regions of said bridge portion.
A window comprising a rigid transparent insulating sheet, a heater grid including conductive strips and bus bands made of a mixture of metallic powder and a frit baked onto a surface of the sheet, and at least one terminal for connection of the grid into an electric circuit, the terminal including two coplanar feet soldered to one of said bus bands, and a strip-shaped bridge portion joined with the feet by shoulder portions and displaced from the plane of said feet, a tab extending laterally from said bridge portion between said shoulder portions with the initial portion of the tab coplanar with the bridge portion, the bridge portion directly between said shoulder portions and in direct lateral alignment with said initial portion of the tab having an opening passing completely therethrough to produce in said bridge portion a region of smaller lateral cross section than other regions of said bridge portion.
